1. Engine Coolant Surge Tankand Pressure Cap
2. Engine Cooling Fan (Out of View)
{Warning
An electric engine cooling fan
under the hood can start up even
when the engine is not running and
can cause injury. Keep hands,
clothing, and tools away from any
underhood electric fan.
{Warning
Heater and radiator hoses, and
other engine parts, can be very hot.
Do not touch them. If you do, you
can be burned.
Do not run the engine if there is a
leak. If you run the engine, it could
lose all coolant. That could cause
an engine fire, and you could be
burned. Get any leak fixed before
you drive the vehicle.
Caution
Using coolant other than
DEX-COOL®can cause premature
engine, heater core, or radiator
corrosion. In addition, the engine
coolant could require changing
sooner. Any repairs would not be
covered by the vehicle warranty.
Always use DEX-COOL (silicate-free)
coolant in the vehicle.
Engine Coolant
The cooling system in the vehicle is
filled with DEX-COOL engine coolant.
See Maintenance Schedule 0324 and
Recommended Fluids and
Lubricants 0331.
The following explains the cooling
system and how to check and add
coolant when it is low. If there is a
problem with engine overheating, see
Engine Overheating 0267.
What to Use
{Warning
Adding only plain water or some
other liquid to the cooling system
can be dangerous. Plain water and
other liquids, can boil before the
proper coolant mixture will. The
coolant warning system is set for
the proper coolant mixture. With
plain water or the wrong mixture,
the engine could get too hot but
you would not get the overheat
warning. The engine could catch

VEHICLE CARE 271
.A fluid leak in the brake hydraulic
system. Have the brake hydraulic
system fixed. With a leak, the
brakes will not work well.
Always clean the brake fluid reservoir
cap and the area around the cap
before removing it.
Do not top off the brake fluid. Adding
fluid does not correct a leak. If fluid is
added when the linings are worn,
there will be too much fluid when
new brake linings are installed. Add or
remove fluid, as necessary, only when
work is done on the brake hydraulic
system.
{Warning
If too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You or
others could be burned, and the
vehicle could be damaged. Add
brake fluid only when work is done
on the brake hydraulic system. When the brake fluid falls to a low
level, the brake warning light comes
on. See
Brake System Warning
Light 0125.
Brake fluid absorbs water over time
which degrades the effectiveness of
the brake fluid. Replace brake fluid at
the specified intervals to prevent
increased stopping distance. See
Maintenance Schedule 0324.
What to Add
Use only GM approved DOT 3 brake
fluid from a clean, sealed container.
See Recommended Fluids and
Lubricants 0331.
{Warning
The wrong or contaminated brake
fluid could result in damage to the
brake system. This could result in
the loss of braking leading to a
possible injury. Always use the
proper GM approved brake fluid.
Caution
If brake fluid is spilled on the
vehicle's painted surfaces, the paint
finish can be damaged. Immediately
wash off any painted surface.
Battery
The original equipment battery is
maintenance free. Do not remove the
cap and do not add fluid.
The battery is in the trunk, behind the
trim panel, on the driver side of the
vehicle. Refer to the replacement
number shown on the original battery
label when a new battery is needed.

296 VEHICLE CARE
Tire Inspection
We recommend that the tires,
including the spare tire, if the
vehicle has one, be inspected for
signs of wear or damage at least
once a month.
Replace the tire if:
.The indicators at three or more
places around the tire can
be seen.
.There is cord or fabric showing
through the tire's rubber.
.The tread or sidewall is
cracked, cut, or snagged deep
enough to show cord or fabric.
.The tire has a bump, bulge,
or split.
.The tire has a puncture, cut,
or other damage that cannot
be repaired well because of the
size or location of the damage.
Tire Rotation
If the vehicle has non-directional
tires, they should be rotated at the
intervals specified in the
Maintenance Schedule. See
Maintenance Schedule0324.
Tires are rotated to achieve a
uniform wear for all tires. The first
rotation is the most important.
Anytime unusual wear is noticed,
rotate the tires as soon as
possible, check for proper tire
inflation pressure, and check for
damaged tires or wheels. If the
unusual wear continues after the
rotation, check the wheel
alignment. See When It Is Time for
New Tires 0297 and Wheel
Replacement 0300.
Directional tires should not be
rotated. Each tire and wheel
should be used only in the
position it is in. Directional tires
will have an arrow on the tire indicating the proper direction of
rotation or will have
“left”or
“right ”molded on the sidewall.
Use this rotation pattern if the
vehicle has different size tires on
the front and rear and they are
non-directional.
Different tire sizes should not be
rotated front to rear.

General Information
Caution
Maintenance intervals, checks,
inspections, recommended fluids,
and lubricants are necessary to
keep this vehicle in good working
condition. Damage caused by failure
to follow scheduled maintenance
might not be covered by the vehicle
warranty.
As the vehicle owner, you are
responsible for the scheduled
maintenance in this section. We
recommend having your dealer
perform these services. Proper vehicle
maintenance helps to keep the vehicle
in good working condition, improves
fuel economy, and reduces vehicle
emissions for better air quality.
Because of all the different ways
people use vehicles, maintenance
needs vary. The vehicle might need
more frequent checks and services.
Please read the information under Scheduled Maintenance. To keep the
vehicle in good condition, see your
dealer.
The maintenance schedule is for
vehicles that:
.
Carry passengers and cargo within
recommended limits on the Tire
and Loading Information label. See
Vehicle Load Limits 0192.
. Are driven on reasonable road
surfaces within legal driving limits.
. Use the recommended fuel. See
Fuel 0242.
{Warning
Performing maintenance work can
be dangerous. Some jobs can cause
serious injury. Perform maintenance
work only if you have the required
know-how and the proper tools and
equipment. If in doubt, see your
dealer to have a qualified
technician do the work. See Doing
Your Own Service Work 0249.

324 SERVICE AND MAINTENANCE
At your dealer, you can be certain that
you will receive the highest level of
service available. Your dealer has
specially trained service technicians,
uses genuine replacement parts, as
well as, up-to-date tools and
equipment to ensure fast and accurate
diagnostics.
The proper replacement parts, fluids,
and lubricants to use are listed in
Recommended Fluids and Lubricants
0331 and Maintenance Replacement
Parts 0332. We recommend the use
of genuine parts from your dealer.
Rotation of New Tires
Tire rotation is not recommended if
the vehicle has different size tires on
the front and rear wheels. If tire
rotation is recommended for the
vehicle, to maintain ride, handling,
and performance of the vehicle, it is
important that the first rotation
service for new tires be performed.
Tires should be rotated every service.
See Tire Rotation 0296.Maintenance Schedule
Owner Checks and Services
At Each Fuel Stop
.
Check the engine oil level. See
Engine Oil 0257.
Once a Month
. Check the tire inflation pressures.
See Tire Pressure 0290.
. Inspect the tires for wear. See Tire
Inspection 0296.
. Check the windshield washer fluid
level. See Washer Fluid 0269.
Engine Oil Change
Change the engine oil and filter when
the CHANGE ENGINE OIL SOON
message displays, 12 000 km/7,500 mi,
or at one year, whichever comes first.
If driven under the best conditions,
the engine oil life system may not
indicate the need for vehicle service
for up to a year. The engine oil and
filter must be changed at least once a
year and the oil life system must be
reset. Your trained dealer technician
can perform this work. If the engine oil life system is reset accidentally,
service the vehicle within 5 000 km/
3,000 mi since the last service. Reset
the oil life system when the oil is
changed. See
Engine Oil Life
System 0259.
Tire Rotation and Required
Services Every 12 000 km/
7,500 mi
Rotate the tires, if recommended for
the vehicle, and perform the following
services. See Tire Rotation0296.
. Check engine oil level and oil
life percentage. If needed, change
engine oil and filter, and reset oil
life system. See Engine Oil0257
and Engine Oil Life System 0259.
. Check engine coolant level. See
Engine Coolant 0264.
. Check windshield washer fluid
level. See Washer Fluid 0269.
. Visually inspect windshield wiper
blades for wear, cracking,
or contamination. See Exterior
Care 0315. Replace worn or
